Abstract
The invention relates to a double-direction relief damper, which can be installed in an underground coal mine. When gas explosion occurs at one side of the underground damper, the damper can automatically release pressure under the action of blast wave to prevent the damper from being damaged by the blast wave and simultaneously ensure that the mine ventilation system is safe and reliable and the ventilation facilities are not damaged, thereby guaranteeing the disaster prevention and defense in the mine, and ensuring the safe production of the coal mine.
Description
Technical field: double-direction relief damper belongs to the Safety of Coal Mine Production technical field, is specially adapted to the coalmine ventilation system and prevents gas explosion, damages underground air door and various ventilation equipment, and the accident that prevents enlarges, and guarantees personnel in the pit's safety, guarantees mine safety.
Background technology: by overall understanding and retrieval, gas explosion when taking place in underground air door at present, unidirectional openability because of air door, caused shock wave to wrack air door and various ventilation equipment, the damage of ventilation system has caused a large amount of personnel's casualties and mine to damage, and has invented double-direction relief damper in order to address the above problem us.
Summary of the invention: the feature of double-direction relief damper is: the main door leaf that will be installed in the doorframe is hollow door leaf, is coupled to each other by the door-hinge hinge between doorframe and the main door leaf; Hollow position on main door leaf is equipped with secondary door leaf, is coupled to each other by the door-hinge hinge between secondary door leaf and the main door leaf; When main door leaf and doorframe were closed, main door leaf just in time was embedded in recessed embedding place of doorframe; Secondary door leaf just in time falls into recessed embedding place of main door leaf when cutting out, simultaneously the hollow position on the main door leaf is all covered completely; Main door leaf is opposite with the opening direction of secondary door leaf, and secondary door leaf leaves doorframe together in company with main door leaf when opening main door leaf; When opening secondary door leaf, secondary door leaf leaves main door leaf, exposes the hollow position on the main door leaf simultaneously, and personnel's article are come in and gone out by the hollow position on the main door leaf; The feature of double-direction relief damper is the no matter any side generation gas explosion in air door both sides, shock wave can be opened the air door pressure release, air door is closed again under the effect of spring automatically after the pressure release, thereby ensure that air door is not destroyed by shock wave, guarantee that simultaneously mine ventilation system is safe and reliable, ventilation equipment is not damaged.
Double-direction relief damper can be installed under the coal mine, when a certain side generation gas explosion of underground air door both sides, air door can be opened pressure release automatically under the effect of shock wave, thereby guarantee that air door is not destroyed by shock wave, guarantee that simultaneously mine ventilation system is safe and reliable, ventilation equipment is not damaged, and the ability thereby the raising mine is prevented and fought natural adversities is guaranteed Safety of Coal Mine Production.
Double-direction relief damper compared with prior art has the following advantages:
1, can be installed in the existing various airways, colliery, and reusable.
2, can play double-direction relief, protrusion-dispelling, explosion-proof effect, when guaranteeing gas explosion, when coal is outstanding, air door is excellent.
3, bidirectional passing, bi-directional door is closed the door, and can adjust air quantity, blast by air door according to the degree of opening door.
4, when meeting gas accident, the quick-recovery ventilation system is normal soon, lays the first stone for rescue and relief work is provided.

Accompanying drawing is the double-direction relief damper schematic diagram.
1, doorframe; 2, main door leaf; 3, secondary door leaf;
4, door-hinge hinge; 5, spring.
The specific embodiment: double-direction relief damper is installed in the underworkings, and its specific embodiment is that the main door leaf (2) that will be installed in the doorframe (1) is hollow door leaf, is coupled to each other by door-hinge hinge (4) between doorframe (1) and the main door leaf (2); Hollow position on main door leaf (2) is equipped with secondary door leaf (3), is coupled to each other by door-hinge hinge (4) between secondary door leaf (3) and the main door leaf (2); Main door leaf (2) and doorframe (1) are when closing, and main door leaf (2) is just in time inlayed recessed embedding place of doorframe (1); Secondary door leaf (3) just in time falls into recessed embedding place of main door leaf (2) when cutting out, simultaneously the hollow position on the main door leaf (2) is all covered completely; Main door leaf (2) is opposite with the opening direction of secondary door leaf (3), and secondary door leaf (3) leaves doorframe (1) together in company with main door leaf (2) when opening main door leaf (2); When opening secondary door leaf (3), secondary door leaf (3) leaves main door leaf (2), exposes the hollow position on the main door leaf (2) simultaneously, and personnel's article are come in and gone out by the hollow position on the main door leaf (2).In addition, between main door leaf (2) and the doorframe (1) spring (5) is installed, makes main door leaf (2) be in normally off.Between secondary door leaf (3) and the main door leaf (2) spring (5) is installed also, makes between secondary door leaf (3) and the main door leaf (2) to be in normally off.After the pressure release that has an accident, air door can be in normally off automatically under the effect of spring (5), thereby guarantees ventilation system safety, reliable.
Claims (2)
1. the feature of double-direction relief damper is: the main door leaf (2) that will be installed in the doorframe (1) is hollow door leaf, is coupled to each other by door-hinge hinge (4) between doorframe (1) and the main door leaf (2); Hollow position on main door leaf (2) is equipped with secondary door leaf (3), is coupled to each other by door-hinge hinge (4) between secondary door leaf (3) and the main door leaf (2); Main door leaf (2) and doorframe (1) are when closing, and main door leaf (2) just in time is embedded in recessed embedding place of doorframe (1); Secondary door leaf (3) just in time falls into recessed embedding place of main door leaf (2) when cutting out, simultaneously the hollow position on the main door leaf (2) is all covered completely; Main door leaf (2) is opposite with the opening direction of secondary door leaf (3), and secondary door leaf (3) leaves doorframe (1) together in company with main door leaf (2) when opening main door leaf (2); When opening secondary door leaf (3), secondary door leaf (3) leaves main door leaf (2), exposes the hollow position on the main door leaf (2) simultaneously, and personnel's article are come in and gone out by the hollow position on the main door leaf (2).
2. the feature of double-direction relief damper is the no matter any side generation gas explosion in air door both sides, shock wave can be opened the air door pressure release, air door is closed again under the effect of spring (5) automatically after the pressure release, thereby ensure that air door is not destroyed by shock wave, guarantee that simultaneously mine ventilation system is safe and reliable, ventilation equipment is not damaged.
